John F. Kennedy Airport has been evacuated after flooding from a water main break.
Footage from the airport in New York showed water pouring into terminal four through the ceiling, with several centimetres of water rising around piles of stacked luggage.
Officials said the terminal and baggage claim were flooded.
By 1pm US time, more than 20 departing flights had been cancelled from JFK with 24 scheduled arrival cancellations and more than 100 flights delayed.
Passengers reported chaos as luggage piled up with several saying there had been a lack of staff and information provided to those stuck in the terminal.
